Digital Forensics

Law enforcement can rarely get through a case these days without having to examine some kind of technology. Computers may not be used to commit a particular crime, but they might contain evidence. Similarly, cell phones and other data devices need to be examined regularly. This has led to the development of the field of digital forensics, which examines how equipment has to be handled to ensure that it hasn’t been altered once it has been taken for evidence, how to copy material reliably, and how to maintain equipment that can sometimes erase itself if left unpowered.
